Static Seals Static Seals - Rubber, PTFE, Metal, Bonded and Inflatable In a static sealing application there is no movement between sealing surfaces or between the seal surface and its mating surface. The most common seal used in static sealing situations is the O-Ring, but in addition to these, O Rings Limited can offer a range of specialized static seals. The range includes our proprietary metal O-Rings, Wills Rings, which are ideal for use in extreme temperatures and pressures. Other static seals we offer include inflatable seals (Airseal), various rubber seals, valve seals, quad rings, square rings, rubber - metal bonded seals, polyurethane seals and spring energized Polytetrafluoroethylene (PTFE) seals. Airseal Airseal is an inflatable seal, vulcanized to specific customer profiles. Being activated by air, water or other medium, this seal represents an economical alternative to conventional gaskets. The large range of profiles and compounds available allows the use of Airseal in various applications, including doors and locks of autoclaves and sterilizers, in the chemical and semiconductor industries. Back-up Ring Back-up Rings are installed together with O-Rings and Quad-Ring Seals to prevent gap extrusion in applications above 5 MPa / 725 psi. Available in solid, split and spiral PTFE, elastomers and thermoplastics based on ISO 3601, AS 568. Bonded Seal Often referred to as Dowty Seals or Washers, these are rectangular section metal washers with a trapezoidal shaped ring of vulcanised rubber bonded to the inside. You can select the material for the washer and the rubbers to best meet the requirement of each application. The seal is primarily used in high-pressure environments where copper washers are unsuitable. Also available as Self Centralising Bonded Seals, these have an extra lip on the ID of the rubber. As its name suggests the extra lip centralises the seal at its location and this helps eliminate leaks. Extra advantages of easy installation and reduced assembly time.
